I always thought Goosebumps was more kids than YA, but the dividing line is always hard to find, and certainly Stine proved there was a fat load of cash in the under 18 market. In the early 80s when I was in the target market YA was Hardy Boys and Judy Bloom, and they kind of sucked. I’m glad the market is finally being addressed.
You may be right about the Goosebumps target market. I didn’t let my daughters read them (not that they wanted to, it seemed to be a boy’s series like I guess Twilight is a girl’s series). The test of any series for kids, though, ought to be whether it leads to adult reading habits beyond the latest romance or Stephen King novels.
I have mostly given up on fiction these days, partly because of their inanity but also to avoid frequently profanity and immoral “heroes”. Besides, I tend to read in quick snatches of time and nonfiction fills the bill. I have my car book, my family room book, my living room book, my bath book, all being read whenever a find a moment to pick to up. I have hundreds of books in my library and find no problem avoiding insipid television or popular fiction.
